Check Digit Verification of cas no

The CAS Registry Mumber 121783-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,8 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121783-18:
(8*1)+(7*2)+(6*1)+(5*7)+(4*8)+(3*3)+(2*1)+(1*8)=114
114 % 10 = 4
So 121783-18-4 is a valid CAS Registry Number.

Convenient Synthesis of Mono and Cyclic Sulphates of Carbohydrates via Triflate Displacement

Latif, Farzana,Shekhani, Mohammed Saleh,Voelter, Wolfgang

, p. 1573 - 1575 (2007/10/02)

The 2,3-anhydropyranoside-4-triflates (1), (3), and (6) react with tetrabutylammonium hydrogen sulphate to afford the sulphate esters (2), (4), and (7) respectively.In the case of triflates (3) and (6) the cyclic sulphates (5) and (8) were obtained as major products.The benzyl pyranoside (8) was successfully deblocked to yield the free sugar cyclic sulphate (9).The 1H NMR spectra of the newly synthesized sulphates have been discussed in detail.The 13C NMR spectral data are also described.
